Abstract
The invention provides a light-emitting diode (LED) dimming circuit which includes that dimming adapter loops are connected in parallel between a mains input end and an LED light source circuit. The LED dimmer circuit solves a problem that the LED light flashes in the prior art.
Description
Technical field
The present invention relates to a kind of circuit, refer to especially a kind of light adjusting circuit for LED light source.
Background technology
Controllable silicon is due to the characteristic with silicon rectification device, can work under high voltage, large current condition, and its course of work can be controlled, therefore be widely used in the electronic circuits such as controlled rectification, AC voltage adjusting, contactless electronic beam switch, inversion and frequency conversion.At lighting field, the thyristor regulating Optimizing Control System all is based on conventional light source and carries out light modulation at present, and such as Halogen lamp LED etc., conventional light source is resistive load substantially, the problem compatible to the control of dimmer.But for throw light on the original controllable silicon of use on the illuminating product of LED dimming control system or dimmer, compatible problem highlights, and substantially stroboscopic all occurs in certain interval of dimming scope.Because the driving governor of LED is capacitive load, can make the distortion of power input voltage waveform generation when original controllable silicon illumination dimming control system or dimmer applications, the driving governor that makes LED is steady operation normally, make LED light source flicker occur, cause and to use the LED product at the place modernization overlay with light modulation, thereby can't realize energy-conserving and environment-protective.
Summary of the invention
The present invention proposes a kind of LED light adjusting circuit, has solved the problem of LED lamp flicker in the prior art.
Technical scheme of the present invention is achieved in that
A kind of LED light adjusting circuit, light modulation adapter in parallel loop between power input and LED light source circuit.
Preferably, the LED light adjusting circuit comprises the LED power circuit and is connected in many LED lamps between LED potential circuit output; The light modulation adapter is connected between the input of LED power circuit.
The present invention is by being attempted by the light modulation adapter on the road, be used for adjusting the voltage and current waveform in whole loop, thereby can well solve the flicker problem, the light modulation adapter can detect the output voltage waveforms of controllable silicon light modulation, if waveform is good, the light modulation adapter need not to process, when waveform voltage produces distortion effects to the flicker of LED lamp, in time from the dynamic response action, waveform voltage is repaired in incision to the light modulation adapter.
Description of drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is a kind of LED light adjusting circuit of the present invention electronic-circuit diagram.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
A kind of LED light adjusting circuit, light modulation adapter in parallel loop between power input and LED light source circuit.
Preferably, the LED light adjusting circuit comprises the LED power circuit and is connected in many LED lamps between LED potential circuit output; The light modulation adapter is connected between the input of LED power circuit.
The present invention is by being attempted by the light modulation adapter on the road, be used for adjusting the voltage and current waveform in whole loop, thereby can well solve the flicker problem, the light modulation adapter can detect the output voltage waveforms of controllable silicon light modulation, if waveform is good, the light modulation adapter need not to process, when waveform voltage produces distortion effects to the flicker of LED lamp, in time from the dynamic response action, waveform voltage is repaired in incision to the light modulation adapter.
The present invention has following advantage:
The output voltage waveforms of detection controllable silicon light modulation that 1, can be intelligent, distorted is automatically to place under repair at once.
If 2, voltage waveform does not have large improvement, the light modulation adapter will further deeply be cut waveform and proofreaies and correct.
3, after voltage waveform became well, the light modulation adapter can attempt excising waveform modification automatically.
The above is only preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
